chore(deps): Remove superfluous dependency (#384)

* chore(deps): Removed deprecated dependency

In #305 @carstencodes removed the implementation of the
existing build task from the build tasks package.

Hence, the dependency to Microsoft.Build.Utilities.Core is
no longer required. This way, we can safely remove the dependency from dscom build tasks.

* chore: Removed obsolete task files and dependencies

In #305 the dSPACE.Runtime.InteropServices.BuildTasks.Task.targets
 was removed. Hence, even the stub implementations of the tasks are not accessible and must not present.

 Therefore the files and the depndencies can be removed safely.
